Acoustic resonances in open systems, which are usually associated with resonant modes
characterized by complex eigenfrequencies, play a fundamental role in manipulating …

Dissipation in mechanics, optics, acoustics, and electronic circuits is nowadays recognized
to be not always detrimental but can be exploited to achieve non-Hermitian topological …

Non-Hermitian matrices are ubiquitous in the description of nature ranging from classical
dissipative systems, including optical, electrical, and mechanical metamaterials, to scattering …

Dimensionality plays a fundamental role in the classification of novel phases and their
responses. In generic lattices of 2D and beyond, however, we found that non-Hermitian …

We predict novel topological phases with broken time-reversal symmetry supporting the
coexistence of opposite chiral edge states, which are fundamentally different from the …

Non‐Hermitian (NH) physics describes novel phenomena in open systems that allow
generally complex spectra. Introducing NH physics into topological metamaterials, which …

The past few years have witnessed a surge of interest in non-Hermitian Floquet topological
matter due to its exotic properties resulting from the interplay between driving fields and non …

We explore anomalous skin effects at non-Hermitian impurities by studying their interplay
with potential disorder and by exactly solving a minimal lattice model. A striking feature of …

Despite its fully unitary dynamics, the bosonic Kitaev chain (BKC) displays key hallmarks of
non-Hermitian physics, including nonreciprocal transport and the non-Hermitian skin effect …

Noninteracting particles in non-Hermitian quasicrystals display localization-delocalization
and spectral phase transitions in complex energy plane that can be characterized by point …
